Answer:
40
Step-by-step explanation:
5x2 is 10 and 10x4=40
To the find average of the test scores, we need to find the mean.
To find the mean, all we need to do is add up all the numbers and then divide the answer by how many numbers there are
81 + 83 + 85 = 249
249 ÷ 3 = 83
Therefore, the new average is 83
Hope this helps
Answer:
Translation
Step-by-step explanation:
To explain say: you should slide a shape vertically or horizontal or in both on the plane to map it.
PS on my program it shows me that answers to study it so I know this is right
We can break it into two parts.
-> First, the rectangle on the bottom is made up of 2 feet x 16 feet. The formula for area of a rectangle is length times width, so in this case it is equal to 32 feet
-> Next, the triangle has sides of 10 feet, 10 feet, and 16 feet. We can calculate that the height is 6. The formula for area of a triangle is base times height divided by two, so,
48 feet
-> Last, we can add the two totals together. 32 feet + 48 feet = 80 feet giving us our final answer of 80 feet². As this answer is not pictured I am going to assume they are not including Heron's formula or other more complex formulas, leading us to the answer of "can't be determined"
Answer:
O can't be determined
Have a nice day! - <em>Note: It depends on the level of your math class for whether the answer "cannot be determined" is correct as it can be determined, just takes more effort than simple one - two-step formulas.</em>
